Metodologías de cálculo para el análisis de fenómenos de resonancia en sistemas eléctricos de potencia

Abstract

The resonance phenomenon can occur in an electrical power system, which is caused by the presence of harmonics in the network, the same ones that are produced by non-linear loads (eg: systems supported by power electronics), therefore their impedance is not constant, and they generate undesired results putting the quality of energy to consumers at risk. Therefore, nowadays research is being carried out to understand nature, such as the consequences that these cause in electrical networks. This study is essential because this phenomenon can damage the circuit of the electrical installation since it conducts high current and voltage values. For this reason, there are several methods to study resonance, but using them is not entirely easy. This document is focused on a bibliographic review and investigation of the methods to calculate the harmonic resonance and then a comparative analysis of the same is carried out. In addition, a new methodology is proposed which helps to detect the resonance in the SEP in a more sensitive way without omitting any components. This is done in DigSILENT PowerFactory software on the IEEE 9-bus test system.
